The lipoids still remaining in the solution are'removed by treatment in a centrifuge or suitable form of filter. The process is carried out at normal temperature-about 60 F.-and it will be found that the resulting solution-which is substantially without taste or smell-contains all the proteins and v vitamines and other valuable food constituents of the meat. The product resulting from my special process can be used in varrious ways, for instance, by addition to ordi- H nary meatextracts or can be administered as a medicinal food in admixture with alcohol
